Name
clear_data_code_2d_modelT_clear_data_code_2d_modelClearDataCode2dModelClearDataCode2dModelclear_data_code_2d_model — Delete a 2D data code model and free the allocated memory.
Signature
Description
The operator clear_data_code_2d_modelclear_data_code_2d_modelClearDataCode2dModelClearDataCode2dModelClearDataCode2dModelclear_data_code_2d_model deletes a 2D data code
model that was created by create_data_code_2d_modelcreate_data_code_2d_modelCreateDataCode2dModelCreateDataCode2dModelCreateDataCode2dModelcreate_data_code_2d_model or
read_data_code_2d_modelread_data_code_2d_modelReadDataCode2dModelReadDataCode2dModelReadDataCode2dModelread_data_code_2d_model.
All memory used by the model is freed.
The handle of the model is passed in DataCodeHandleDataCodeHandleDataCodeHandleDataCodeHandledataCodeHandledata_code_handle.
After the operator call it is invalid.
For an explanation of the concept of the 2D data code reader
see the introduction of chapter Identification / Data Code.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
This operator modifies the state of the following input parameter:
During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.
Parameters
DataCodeHandleDataCodeHandleDataCodeHandleDataCodeHandledataCodeHandledata_code_handle (input_control, state is modified) datacode_2d → HDataCode2D, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the 2D data code model.
Result
The operator clear_data_code_2d_modelclear_data_code_2d_modelClearDataCode2dModelClearDataCode2dModelClearDataCode2dModelclear_data_code_2d_model returns the value 2 (
H_MSG_TRUE)
if a valid handle was passed and the referred 2D data code model can
be freed correctly.
Otherwise, an exception is raised.
